Description

Technical Field

[0001] This utility model relates to the field of crystal oscillator testing technology, specifically to an auxiliary debugging device for testing a temperature-controlled crystal oscillator. Background Technology

[0002] A cryogenic crystal oscillator is a high-precision frequency control device that minimizes frequency drift caused by temperature changes by placing the crystal oscillator in a temperature-controlled environment. To ensure that the performance of the cryogenic crystal oscillator meets expectations, specialized testing and debugging equipment is required.

[0003] Existing testing devices can be referenced from Chinese Utility Model Patent Publication No. CN219758336U, which discloses a quartz crystal oscillator testing device, including a frame and a tester body. Support columns are installed at the four corners of the lower surface of the frame, and a conveyor belt is connected to the top of the frame. Two sets of mounting brackets are provided in the middle of the outer walls on both sides of the frame. A top plate is installed between the four sets of mounting brackets. An electric telescopic rod is connected to the middle of the lower surface of the top plate, and the bottom end of the electric telescopic rod is connected to the upper surface of the tester body. A test probe is connected to the output end of the tester body. A housing is installed in the middle of the lower surface of the frame. A moving mechanism is provided inside the housing. The moving mechanism includes two sets of moving toothed plates. L-shaped connecting rods are installed at the outer ends of the upper surfaces of the two sets of moving toothed plates. Clamping plates are provided at the bottom of the two sets of L-shaped connecting rods. This can clamp different models of quartz crystal oscillators to be tested, preventing the quartz crystal oscillators from shifting during the test and improving the accuracy of the quartz crystal oscillator test.

[0004] The above-mentioned device has a good effect, but there are still some defects in actual use: the above-mentioned device can drive the rotating shaft and rotating gear to rotate forward or reverse through the operation of the stepper motor. Since the rotating gear is meshed with two sets of moving tooth plates, and the top of the two sets of moving tooth plates is limited by the sliding connection between the moving rod and the slide groove, the two sets of moving tooth plates can move in opposite directions, so as to adjust the distance between adjacent clamping plates and clamp different models of quartz crystal oscillators to be tested.

[0005] However, because the clamping plate in this device has a fixed design, it may not be able to provide effective clamping force or the correct clamping position for quartz crystal oscillators of different sizes and shapes. This limits the application range of the device and may lead to deviation or instability during the test, affecting the accuracy of the final test results. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary debugging device for testing constant temperature crystal oscillators. This device features flexible adjustment and excellent clamping performance. Through the design of a first and second sliding rod and a second clamping plate, the device can flexibly adapt to crystal oscillators of various specifications. The first and second telescopic rods provide additional adjustment capabilities, allowing the clamping assembly to be fine-tuned according to crystal oscillators of different sizes and shapes. The design of the limiting sleeve ensures the stability and guidance of the sliding rods during sliding, preventing deviation and thus guaranteeing consistency and accuracy during testing.

A fixing plate is provided above the two first clamping plates, and the bottom of the two fixing plates is fixedly connected to the opposite side of the two first clamping plates.

[0012] As a preferred embodiment of the constant temperature crystal oscillator testing and debugging device of this utility model, both of the fixed plates are slidably connected to lifting blocks inside. The left and right ends of the two lifting blocks are respectively rotatably connected to a first fixed sleeve and a second fixed sleeve that are inclined. The first fixed sleeve and the second fixed sleeve are symmetrically arranged on the left and right sides of the lifting blocks. One end of the top of the first telescopic rod extends into the interior of the first fixed sleeve and is slidably connected thereto. One end of the top of the second telescopic rod extends into the interior of the second fixed sleeve and is slidably connected thereto.

The first and second fixing sleeves are equipped with first and second springs, respectively, providing buffering and rebound force for the first and second telescopic rods, ensuring moderate clamping force and preventing over-clamping or loosening. Under the action of the power, the first clamping plate moves inward, and simultaneously, the second clamping plates on the first and second sliding rods also move towards the center, ultimately securing the crystal oscillator stably through the four rubber pads.

[0027] The first clamping plate 10 is fixedly installed via an L-shaped connecting rod 9 and can slide symmetrically back and forth on the top of the conveyor belt 3 to adjust its relative position to accommodate crystal oscillators of different sizes. Each first clamping plate 10 has four second clamping plates 13 slidably connected to both sides. These second clamping plates 13 can slide freely on the top of the conveyor belt 3, further enhancing adaptability to crystal oscillators of different sizes. Rubber pads 14 are fixedly connected to the four second clamping plates 13 on their closest sides, which not only protect the crystal oscillator from hard compression damage but also increase friction to ensure that the crystal oscillator does not move during testing.

The bottom of the mounting brackets 4 is fixedly connected to the front and rear surfaces of the frame 1 respectively.

[0031] Two clamping plates 10 are slidably connected to sliding rods 11 and 12 on their left and right sides, respectively. A clamping plate 13 is fixedly connected to the end of each sliding rod 11 and 12 away from the clamping plate 10. Limiting sleeves 15 are fixedly installed at the top and bottom positions inside the two clamping plates 10. The ends of the sliding rods 11 and 12 away from the clamping plate 13 extend into the two limiting sleeves 15 and are slidably connected to them, ensuring stability and guidance during sliding.

[0032] Furthermore, a telescopic rod 16 is rotatably connected to the top of the surfaces of the two sliding rods 11, and a telescopic rod 17 is rotatably connected to the top of the surfaces of the two sliding rods 12. The telescopic rods 16 and 17 are symmetrically arranged on the left and right sides of the clamping plate 10. A fixing plate 18 is provided above the two clamping plates 10, and the bottom of the two fixing plates 18 is fixedly connected to the opposite side of the two clamping plates 10.

[0033] The top surfaces of slide rod 11 and slide rod 12 are rotatably connected to telescopic rod 16 and telescopic rod 17, respectively, and are symmetrically arranged on the left and right sides of clamping plate 10, providing additional adjustment capability and flexibility. Each clamping plate 10 has a fixing plate 18 above it, and the bottom of each fixing plate 18 is fixedly connected to the opposite side of the clamping plate 10, enhancing the overall structural stability.

[0034] Furthermore, both fixed plates 18 are slidably connected to lifting blocks 19 inside. The left and right ends of the two lifting blocks 19 are respectively rotatably connected to a first fixed sleeve 20 and a second fixed sleeve 21 that are set at an inclination. The first fixed sleeve 20 and the second fixed sleeve 21 are symmetrically arranged on the left and right sides of the lifting blocks 19. One end of the top of the first telescopic rod 16 extends into the first fixed sleeve 20 and is slidably connected to it. One end of the top of the second telescopic rod 17 extends into the second fixed sleeve 21 and is slidably connected to it.

[0035] Two lifting blocks 19 are rotatably connected to inclined fixing sleeves 20 and 21 at their left and right ends, respectively. Fixing sleeves 20 and 21 are symmetrically arranged on the left and right sides of the lifting blocks 19. One end of the top of the first telescopic rod 16 extends into the first fixing sleeve 20 and is slidably connected thereto. One end of the top of the second telescopic rod 17 extends into the second fixing sleeve 21 and is slidably connected thereto.

[0036] Furthermore, a first spring 22 is provided inside the first fixing sleeve 20. One end of the first spring 22 is fixedly connected to one side of the inner wall of the first fixing sleeve 20, and the other end of the first spring 22 is fixedly connected to one top end of the first telescopic rod 16. A second spring 23 is provided inside the second fixing sleeve 21. One end of the second spring 23 is fixedly connected to one side of the inner wall of the second fixing sleeve 21, and the bottom end of the second spring 23 is fixedly connected to one top end of the second telescopic rod 17.

[0037] With the design of the lifting block 19 and the inclined first and second fixing sleeves 20 and 21, the device can flexibly adapt to various sizes of crystal oscillators. The top ends of the first and second telescopic rods 16 and 17 extend into and slide into the corresponding fixing sleeves, providing a greater adjustment range and flexibility. The spring assemblies (first spring 22 and second spring 23) are designed to provide cushioning and rebound force as the first and second telescopic rods 16 and 17 move, helping to maintain the stability and consistency of the clamping assembly and preventing over-clamping or loosening.

[0038] Furthermore, each of the two lifting blocks 19 has a lifting threaded rod 24 rotatably connected to its internal center, and each of the two lifting threaded rods 24 has a clamping plate 10 rotatably connected to its bottom. The tops of the two lifting blocks 19 extend to the outside of the fixed plate 18 and are fixedly connected to a power motor 25. The two power motors 25 are fixedly installed at the top center of the two fixed plates 18.

[0039] Furthermore, lifting limit rods 26 are provided on the left and right sides inside the two fixed plates 18. The top of the lifting limit rods 26 is fixedly connected to the top of the inner wall of the fixed plate 18, and the bottom of the lifting limit rods 26 is fixedly connected to the top of the first clamping plate 10. The two lifting limit rods 26 located on the left and right sides inside the same fixed plate 18 are slidably connected to the left and right sides of the lifting block 19.

[0040] The design of the lifting threaded rod 24 and the power motor 25 enables precise control of the vertical position of the clamping plate 10, thereby adapting to crystal oscillators of different heights. The design of the lifting limit rod 26 not only provides additional support but also restricts the movement path of the lifting block 19, ensuring its stable movement in the vertical direction and preventing deviation.

[0041] The crystal oscillator under test is placed on conveyor belt 3 and automatically transported to the test position. The electric telescopic rod 6 controls the height of the tester body 7 to ensure that the test probe 8 contacts the crystal oscillator under test accurately. The power motor 25 drives the lifting threaded rod 24 to rotate, causing the lifting block 19 to slide up and down along the inside of the fixed plate 18, thereby precisely adjusting the height of the first clamping plate 10 to accommodate crystal oscillators of different heights.

[0042] Once the crystal oscillator reaches the predetermined position, the power motor 25 stops operating. At this point, the first clamping plate 10 is at the appropriate height. The first sliding rod 11 and the second sliding rod 12 on both sides of the first clamping plate 10 are respectively connected to the second clamping plate 13. These sliding rods are guided by the limiting sleeve 15 to ensure smooth sliding. The top ends of the first telescopic rod 16 and the second telescopic rod 17 extend into and slide inside the inclined first fixing sleeve 20 and the second fixing sleeve 21. The first fixing sleeve 20 and the second fixing sleeve 21 are equipped with a first spring 22 and a second spring 23 to provide buffering and rebound force for the first telescopic rod 16 and the second telescopic rod 17, ensuring that the clamping force is moderate and preventing over-clamping or loosening. Under the action of the power, the first clamping plate 10 moves inward, and at the same time, the second clamping plate 13 on the first sliding rod 11 and the second sliding rod 12 also moves towards the center, finally clamping the crystal oscillator stably through the four rubber pads 14.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
